To all whom "it may concern:

Be it known that I, ADOLPH SANDERS, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful 1m roveinents in Time-LimitAnnunciators and tegisters, of which thelol lowing is a specification.

The object of my invention is to afford a simple and effective device bymeans of whichthe number and length of tele hone calls may be announcedand registerer and which may be used for various similar purposes, asfor the keeping of games played upon a time basis.

.The invention consists essentially in the combination with a clockmovement, of the special construction and arrangement of reg isteringand announcing mechanism hereinafter described and claimed specifically.

In the accompanying drawings, Figure l, is a front elevation of myannunciator closed; Fig. 2, is a front elevation with the door 0 ned;Fig. 3, is a front elevation full size 0 the operative arts, the dialsand ointers being omitted; ig. 4, is a side elirvation of announcing anreg stering mechanism shown in Fig. 3, only parts of the clock move mentand frame being included; Fig. 5,, is a and adjacent parts, taken frombelow and looking upward Fig. 8, is a view similar to Fig. 6, and Fig.9, a view similar to Fig. 7, show the position of the nuts when the camw eel is disconnected l s indie, Fig. 10, is a rear elevation showing te means for operating the indicating and re istering mechanism.

n making my annuncietor I employ an ordinary clock movement with theexception of the hour hand and connections. In the drawings parts onlyof a double spring long time movement are shown sullicient to illustratethe embodiment of my invention in practical form, 1, being the usualmain or minute hand spindle on which in. the present case is rigidlysecured the ratchet wheel 2, on the hub 3 of which is a slidablc disk 4mounted on the inner end of a spring late 5, the outer end of which issecured rigin ly at 6 rorn the main to the frame f. 011 the main spindle1 in front of the ratchet wheel 2 is loosely mounted a cam wheel Chaving a hub on which is a disk 0, to the'rearside of which a pawl 13,is pivotally attached, said disk c, also carrying a sprin c, which tendsconstantly to hold the paw c, in engagement with-the teeth. of theratchet wheel 2 as shown in Figs. 6 and 7. An inclined pin or shoulderc, on the pawl c, engages with the edge. of the disk 4, so that when thedisk 4 is forced backward against the resistance of the spring plate 5,the pawl 0', will he raised from engagement with the teeth of theratchet wheel 2 against the resistance of the s ring c, as shown inFigs. 8 and 9, there y disconnecting the cam wheel C from the spindle 1.The s n'ing plate 5 is depressed by means of a racing arm a, pivotallymounted on a stud a, attached to the frame f, the inner end of therocker arm a, resting upon the face of said spring plate and its outerend being formed with an inclined edge a, for engagement with the u perend 8, of the switch lever S. Thus w en the switch lever S is turnedfrom right to left its upper end Wlll act against the inclined edge a",to depress the s rin 5, and disconnect the cam wheelCfrom t is c ockwork as above described, whereas when said switch lever Sis turned fromleft to right its end will be withdrawn from the inclined edge (1thereby allowing the spring 5 to advance the disk 4, and the spring 0 toreengage the pawl c, with the teeth of the ratchet wheel 2, therebyrecoupling the cam wheel C with the clock movement. Stops e,

8, limit the movement of the switch lever in either direction; and itstwo positions are indicated on the face of thedoor of the casing by thewords Qii' and On the first indicat ing that the annunciator mechanismis disconnected from the clock movement which is then running free andthe letter that the onnunciator mechanism is connected with the clockmovement and working in conjunction therewith. i The upper arm of theswitch lever S is pivotally c'omiected by means of a link I, with whatmay be ders'gpa'ted as theregistering lever R by which t e train ofregister" wheels are actuated. A pin 1', upon the t, rests in a slot 1',in theregistermg lever B, the inner edge of the slot being held normal}against said pin 1', by means of a retract e spring l, attached to oneend of the registering lever R, and at the other to a ost Z, on thel'rame f. This arra ment maintains the engagement of the link with theregisterin a lever R while permitting the latter to roc independently onits fulcrum T, when actuated by the cam wheel 0.

The cam wheel C, like the minute hand for which it is substituted,travels, when connected with the clock movement as hereinbeforedescribed, at the rate of one revolution an hour, and hence preferablyis divided into twelve equi-distant eripher'al cams 0, each representinga period of five minutes, which is the usual time measurement for telehone calls &c. It may however obvious y be sub-divided into any desirednumber of eripheral cams c, correspondin to ot er periods or divisionsof time and do not restrict myself in. this respect.

When the switch lever S is swung to the left into the Off position, theregistering lever R is rocked by the link I, away from the cam wheel C,so that the cams c, thereon cannot act upon the awl r, mounted u on theupper ortion o the lever R ien the switch ever S is turned to the rightinto the On osition the sprin 1, holds the registering leve'r R against51c stop 1', in which osition the end of the pawl 7", protrudes into thepath of the cams c, and said pawl being held by a spring 1", against astop 1' the cams c, as they pass push the end oi the pawl away fromthem, thereby rocking the registering lever on its fulcrum r, againstthe resistance of the spring 1*! As a result during the retractilemovement of the re tering lever effected by the spring I, the i ilurcated lower end of the re isterin lever B, acting on the in e, on tiepaw plate E, causes the paw e, to advance the ratchet wheel G, on thearbor g, on which the pinions and g, are mounted. The

inion g mes as with a gear h, on the arbor carrying a pointer Jt, whichat each thrust of the pawl e, indicates one point on the dial h. Thepinion g, engages with a gear '5, on the arbor t, carryin a pinion i,and a pointer i which latter in 'cates the number of revolutions made bythe arbor it, while the pinion 17, engages with a wheel 3', on the arborj, carrying a pointer j, which indicates on the dial the number ofrevolutions of the arbor '21. Obviously an desired train of registeringgears and dia s may be used. The pawl plate E is pivotally supported onthe arbor g, and carries a sprin e, which insures the en agement of thepaw c, with the teeth of tire ratchet wheel G. e, is a stop forsupporting the plate E in its retractile position. The earns a, on thewheel 0 also actuate a bell lever B, when the pawl b, thereon protrudesinto the path.

his pawl is held normall against a stop b, b a spring 6'; and the belever B isretracte to carry the pawl b, beyond the path of the earns a,by a shoulder s, on an extension 8, of the switch lever 8. Thus theswinging of the latter from right to left not only depresses the springplate 5 and releases the cam wheel C from the clock movement, but itsimultaneously retracts the levers R and B.

The springs r and b allow the pawls r and b, to yield before theretractile revolu tion of the cam wheel C, which is effected by means ofa siring m, attached at one end to the hub oi the cam wheel 3 and at theother to a stud m, on the frame f. The lower end of this spring windsaround the hub of said wheel as it is advanced by the clock movement,and directly the wired is released from the latter it returns the wheelto its first position, or position of rest in which the stop 0 on theback of the disk c, rests against a stop f on the frame as shown in Fig.4.

The clock movement is mounted upon a back plate N, attached to asuitable casing n, provided with a hinged front door n, having a looka". Openings in the door expose the several dials to view, includin thedial O, for the pointer c, on the hub the cam wheel C. The handle of theswitch lever S protrudes through a slot 12 in the door.

Normally w hen the device is not in actual use the switch lever S isturned to the left or Ofl osition, in which the clock movement isdisconnected from the announcing and registering mechanism. The movementof the switch lever to the right or On position not only connects thecam wheel with the clock movement, but also registers one call on thedial. The actual time of the whole call will be indicated in minutes bythe pointer c, on the dial 0. At the expiration of each five minutes thecame 0, acting through the registering lever R and bell lever B, willregister and announce the expiration of such term. At theend of the cathe switch lever is turned to the left restoring the parts to theirfirst or normal psliigons, with the pointer c, at O on the la What Iclaim as m invention and desire to secure by Letters atent is,
